PASTING APPARATUS FOR BAG-MACHINES, &C.

Specification of Letters Patent No.

To all whom it may concern:

Be it known thatAI, S. E. PETTEE, of Mansfield, in the county of Bristoland State of Massachusetts, have invented certain new and usefulImprovements in the Construction of Pasters for Bag-Machines (Envelop-Machines) and Similar Purposes; and I hereby declare the following tc bea full, clear, and exact description of the construction and operationof the same, due reference being had to the accompanying drawings, inwhich- Figure l is a view of the paster. Fig. 2 a vertical sectionthrough the center. F ig. 3 shows the bott-om of same, the same lettersindicating the same parts in each.

To construct my improvements make a reservoir to contain the paste ofsuch form as deemed most convenient to use in the machine as A Figs. land 2. In the bottom of this make a hole or cavity in which place ltheroll B so tted as to fill and iit the cavity so as to prevent the escapeof the paste except on the side C on .which is the wedge shaped piece D,which fits the remainder of the cavity when slid clear up but onwithdrawing it, it shall make a gradually increasing opening next to thewheel, this piece D is secured in place and adjusted by means of thescrew E passing through a slot in the side of the cavity, the roll Bturns on `the pivot F and its surface is slightly roughened, not for thepurpose of holding or drawing out the paste but to cause it to 22,199,dated November 80, 1858.

\ catch or hold on the surface of the material to which the paste is tobe applied, to be turned thereby.

In operation the reservoir supplied with paste and the paster so placedin the machine that the surface of the paper shall rub against the rollB and turn in the direction of the arrow in F ig. 2 and by loosening thescrew E and shifting the position of the piece D more or less paste isallowed to pass out with the surface of the roll and by it be depositedon the paper, thus giving complete control over the pasting.

I am aware that rolls placed in open bottoms of vessels have been usedsaid rolls having cavities or cells to convey the paste to the paper,these I do not claim, but

that I claim as new and desire to secure by Letters Patent is-Controlling the flow or draft of the paste when carried from a reservoirby a wheel or roll placed in a passage through the bottom of saidreservoir the roll receiving its motion from the passage of the paperunder it, .when said controlling is effected by means of the piece D andscrew E in the manner and for the purposes above set forth anddescribed. s

In testimony whereof I have hereunto setmy hand in the presence of twowitnesses.

i S. E. PETTEE.
